Home Uterine Activity Monitoring (CPB 0127, reviewed 2026-03-19)
Summary
Aetna considers home uterine activity monitoring (HUAM) experimental, investigational, or unproven. Aetna may consider HUAM medically necessary on an individual case exception basis, after review of each circumstance, for pregnant women with gestational age greater than 18 weeks who cannot feel their contractions and have one of the listed complications, such as incompetent cervix, placenta previa with hemorrhage, a history of classical cesarean section or deep myomectomy, physiologic or anatomic factors such as paralysis or neuromuscular disorders, triplet or greater multiple gestations, preterm labor where conventional arrest methods have failed, or a positive fetal fibronectin test with cervical changes between 20 and under 36 weeks despite multiple tocolytics. HUAM is not considered medically necessary in twin gestations unless other extenuating circumstances exist.
